Patent GB-274575-A (GB)
Abstract: 274,575. Rickets, W. J. April 24, 1926. Electromagnetic current and pressure meters; power meters.-In an electric measuring instrument the torque produced by the reaction between the currents passing through the coils of a system is balanced and the removable coil brought back to zero position by a magnetic field due to a direct current, the measure of which gives the indication required. Fig. 1 shows an electrodynamometer having a fixed coil 1 and a moving coil 2. Attached to the moving coil 2 and rotatable coaxially therewith is the movable element 3 of an ammeter or galvanometer of any type, shown as a coil moving in the field of a permanent magnet. Alternatively an iron member of permanent magnet may move in the field of a fixed coil system. In a modification, the moving coils 2, 3 are mounted on separate axes, preferably parallel, which carry light yokes connected by thin threads or otherwise. To operate the instrument as an ammeter, for example, the current to be measured is passed through the coils 1, 2 and a direct current is passed through the coil 3 and adjusted until the resulting torque balances that due to the interaction of the coils 1, 2, so that the system is brought back to zero. The current passing through the coil 3 is a function of the current to be measured. The instrument may similarly be employed as a volt meter or wattmeter. Fig. 3 shows ar alternating-current wattmeter in which a single moving coil 2 is employed both as an alternating current pressure coil and a control coil supplied with direct current from a battery 15. A choking-coil 12 prevents appreciable flow of alternating-current in the direct-current circuit and a condenser 8 prevents direct current from entering the alternating-current circuit. The moving coil 2 is situated in the magnetic field of a permanent magnet 16, Fig. 4, with laminated pole-pieces 17. Two fixed coils 1, 1<a> are pro vided as the equivalent of the coil 1, Fig. 3, and are arranged to yield a narrow but intense field cutting the vertical parts of the rectangular moving coil 2, which are situated at a relatively great distance from the axis to increase the torque. The magnetic path may contain iron The moving coil 2 may be replaced by an astatic combination of two coils 2b, 2<c> as shown ir Fig. 6. '

Title: Method of detecting a leak in a vacuum interrupter
IPC: H01H33/56
Filed: 1974-06-21
Abstract: 1469146 Vacuum switches GENERAL ELECTRIC CO 21 June 1974 [11 July 1973] 27759/74 Heading H1N The invention relates to methods of leak detection in a vacuum-type circuit breaker in which the circuit breaker includes a housing 10 filled with pressurized insulating gas, e.g. SF6, containing a plurality of series-connected vacuum interrupters 20 of conventional design operatively interconnected via a ladder-type linkage 42, 42 and overtravel devices 55 (Figs. 3 and 4, not shown), to an operating rod 45 which is disconnectably coupled to a closing mechanism 65 by a pin 67. The gas pressure tends to hold the interrupter contacts 26, 27 closed and also exerts an ejecting force on the operating rod 45 at the entry point to the housing where it is sealed by a bellows 47 and the breaker opening force is derived from a spring 50 bearing against a thrust plate 52 on to a shoulder 54 on the operating rod, which spring force can be rendered ineffective by operating jack screws 68 to move the thrust plate 52 clear of the shoulder 54. To test for a major leakage in any interrupter 20 the circuit breaker is opened, the closing mechanism disconnected by removing the pin 67 and the net force on the operating rod 45 is then measured and compared to a standard value with the interrupters intact and when the gas pressure (gauge 15) is at a given value, due allowance being made for the force exerted by the opening spring 50. For more accurate assessment the additional step of rendering the opening spring 50 ineffective can be taken before the net force is measured. For minor leaks an electrical test method of applying a voltage across the plurality of interrupters (circuit breaker open) results in a glow discharge within a leaky interrupter and by making the interrupters with translucent casings the discharge can be detected externally of the housing 10 through a lightsensitive device 75.
